Trader consensus heavily favors 16°C (57.5% implied probability) as Tokyo's highest temperature on March 22, driven by the latest Japan Meteorological Agency (JMA) forecast models projecting a mild late-winter day with a peak near 16°C amid persistent cool northerly flows. Ensemble predictions from ECMWF and GFS align closely, showing low confidence for exceeding 17°C due to stable jet stream positioning suppressing warmer air advection. Recent observations confirm below-average March temperatures so far—averaging 13-14°C highs—with urban heat island effects adding only 1-2°C. Historical data for March 22 averages 15°C, positioning 15°C (29%) and 17°C (12%) as credible alternatives, while extremes fade absent sudden regime shifts. JMA's next update tomorrow could refine these odds.
